Hi John,
I have a concern with your exclusion of the surface from the term sea_water_temperature. What Standard Name would you use for the temperature data stream in a CTD profile that extends from the surface to depth? I'm more comfortable with the idea of keeping sea_water_temperature vague so it can include a mixture of surface and within water body measurements, but making the SST terms explicitly exclude temperatures within the water body.
Cheers, Roy.

Alison,
You do impressive work.

In response to the discussion I propose to add the following sentence: 'Sea temperature is the in situ (bulk) temperature of the sea water, not the surface or skin temperature.'
In the proposed definition, do you mean to say 'Sea water temperature is ...' ?
Regarding the existing salinity quantities, the straightforward conclusion (though not implementation) is to make parallel changes to those quantities, and add parallel quantities at least for sea_water_practical_salinity, on the assumption that the users of the original quantities would need the replacement and practical is a likely replacement (I'm guessing here).
However, to a degree this violates the 'wait for demand' principal of CF. A solution might be to put out the question, for each original quantity together with each new salinity (practical, absolute, preformed) "Do you need this value, and if so, would you suggest a correction to the definition?" Those with the needs could check the appropriate boxes, and you could backfill any others that are needed later.
